November 2008, 5 Difficulties of potential control It is not possible to measure the potential of the working electrode  potential difference w.r.t.
{"Image DocumentName": "Difficulties of potential control", "Image ImageDescription": "It is not possible to measure the potential of the working electrode \uf0e0 potential difference w.r.t. reference electrode. Reference electrode is always required. Controlling potential is a lot more difficult than controlling current. This increases the probability of an experiment going wrong.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
